Answer:
x = (-12/7 , 0)
y= (0,4)
Step-by-step explanation:
Plug y=0 into the equation and solve the resulting equation 7x=−12 for x
7x = -12
/7 /7
x = -12/7 and y =0
Plug x=0 into the equation and solve the resulting equation −3y=−12 for y
-3y = -12
/-3 -3
Y = 4 and X = 0
I believe the sum of the interior angles is the number of sides (n), subtracted by 2, and multiplied by 180.
(n - 2) x 180 = sum of interior angles of a n-gon
I also believe that the sum of exterior angles of a n-gon equals to 360 degrees.
There is no congruence between the triangles based on the given information. In general, two sides and an angle not between them are insufficient to specify the triangle completely. In this case, the angles that are congruent are adjacent to non-corresponding sides, so even if SSA correspondence were sufficient to ensure congruence, it would not be sufficient in this case.
The appropriate choice is
... none
Answer:
x=4
Step-by-step explanation:
4x-3=x+9
4x-x-3=9
4x-x=9+3
3x=9+3
3x=12
3/3
12/3=4
x=4
